Radio Japan Bengali on new 11965 kHz - Wrong Frequency choice ?

Radio Japan Bengali service changed its frequency to 1165 kHz (ex 6155 kHz) at 1300-1345 UTC with effect from 23rd May 2010, how this seems to be a wrong frequency choice as TRT (Voice of Turkey) uses the same frequency 11965 kHz for their Russian service at 1300-1355 UTC using a 500 kW transmitter.

Consequently co-channel interfernce was noted by many on the first day of thier transmission, here's how it sounded in New Delhi :

The old frequency 6155 kHz also suffered due to co-channel QRM from CNR 2 at 1000-2300 UTC using a 150 kW txer.
